An Algorithm for the Analysis of the 3D Spatial Organization of the Genome.
No full textWe present an algorithm, and its MATLAB implementation, based on mathematical methods to detect and localize 3D multicolor DNA FISH spots in fluorescence cell image z-stacks. This algorithm provides a method to measure the relative positioning of spots in the nucleus and inter-spot distances with the aim to enrich our understanding of the 3D spatial organization of the genome within the cell nucleus
β2-Adrenergic receptors and G-protein-coupled receptor kinase 2 in rabbit pleural mesothelium
No full textFormer studies on net rate of liquid absorption from small Ringer or 1% albumin-Ringer hydrothoraces in rabbits indicated that Na+ transport and solute-coupled liquid absorption by mesothelium is increased by pleural liquid dilution, and stimulation of β2-adrenoreceptors (β2AR). In this research we tried to provide molecular evidence for β2AR in visceral and parietal mesothelium of rabbit pleura. Moreover, because prolonged stimulation of β2AR may lead to desensitization mediated by G-protein-coupled receptor kinase 2 (GRK2), we also checked whether GRK2 is expressed in pleural mesothelium. To this end we performed immunoblot assays on total protein extracts from scraped visceral and parietal mesothelium, and from cultured pleural mesothelial cells of rabbits. All three samples showed β2AR and GRK2 specific band

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

A new metastable crystalline phase in the Cr-Zr system
No full textA new metastable phase formed during cooling of Zr-Cr alloys with a 36 at% Zr and 64 at% Cr nominal composition has been found during Transmission Electron Microscopy (TEM) studies. The new phase crystallizes in an fcc structure with lattice parameter of 0.817 rim and a chemical composition close to the equiatomic composition. (C) 2009 Elsevier Ltd. All rights reserved
